New mandatory evacuation orders have been issued for the areas of Montecito, Summerland and some parts of Santa Barbara city, emergency officials said. Above graph shows carbon monoxide (CO) and carbon dioxide (CO₂) levels from December 5 - 20, 2017, while the map below shows the location of the measurements (and forecasts). The graph shows levels at one location and for one time of day (00:00 UTC for CO, respectively 01:30 UTC for CO₂). On December 11, 2017, at this location, but at 22:30 UTC, CO levels were 55639 ppb and CO₂ levels were 898 ppm, as illustrated the combination image below (left panel). The right panel of the image below shows that CO₂ levels were as high as 922 ppm on December 7, 2017, at 01:30 UTC at a slightly different location. No CO₂ measurements were available for December 9 and 10, 2017, but given that levels of CO₂ and CO typically go up and down hand in hand, CO₂ may have peaked at well over 1000 ppm on December 9, 2017, possibly exceeding the 1...
